IWI(4) FreeBSD Kernel Interfaces Manual IWI(4)
NAMEiwi -- Intel PRO/Wireless 2200BG/2225BG/2915ABG IEEE 802.11 driver
SYNOPSIS
To compile this driver into the kernel, include the following lines in
your kernel configuration file:
deviceiwideviceiwifwdevicepcidevicewlandevicefirmware
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_iwi_load="YES"
In both cases, place the following line in loader.conf(5) to acknowledge
the firmware license (see below):
legal.intel_iwi.license_ack=1
DESCRIPTION
The iwi driver provides support for Intel PRO/Wireless 2200BG/2915ABG
MiniPCI and 2225BG PCI network adapters. iwi supports station, adhoc,
and monitor mode operation. Only one virtual interface may be configured
at any time. For more information on configuring this device, see
ifconfig(8).
This driver requires the firmware built with the iwifw module to work.
For the loaded firmware to be enabled for use the license at
/usr/share/doc/legal/intel_iwi/LICENSE must be agreed by adding the fol-
lowing line to loader.conf(5):
legal.intel_iwi.license_ack=1

EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev iwi0 inet 192.168.0.20 \
netmask 0xffffff00
Join a specific BSS network with network name ``my_net'':
ifconfig wlan create wlandev iwi0 ssid my_net up
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev iwi0 ssid my_net \
wepmode on wepkey 0x1234567890 weptxkey 1 up
Join a specific BSS network with 128-bit WEP encryption:
ifconfig wlan create wlandev iwi0 wlanmode adhoc ssid my_net \
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
DIAGNOSTICSiwi%d:devicetimeout The driver will reset the hardware. This should
not happen.
iwi%d:firmwareerror The onboard microcontroller crashed for some rea-
son. The driver will reset the hardware. This should not happen.
iwi%d:timeoutwaitingforfirmwareinitializationtocomplete The
onboard microcontroller failed to initialize in time. This should not
happen.
iwi%d:couldnotloadfirmwareimage'%s' The driver failed to load the
firmware image using the firmware(9) subsystem. Verify the iwifw(4)
firmware module is installed and the license agreement loader(8) tunable
has been set.
iwi%d:couldnotloadbootfirmware An attempt to upload the boot
firmware image to the onboard microcontroller failed. This should not
happen.
iwi%d:couldnotloadmicrocode An attempt to upload the microcode image
to the onboard microcontroller failed. This should not happen.
iwi%d:couldnotloadmainfirmware An attempt to upload the main
firmware image to the onboard microcontroller failed. This should not
happen.
